What is the economic power of the United States after World War II?

The post-World War II period was a period of rapid economic development in the United States! I wonder how you define decline? The postwar U.S. economy has experienced only a trough of development and a decline at the end of the war.

It is worth mentioning that the United States made a major turning point in economic management after World War II: the United States and other Western capitalist countries frequently broke out in economic crises before the war, that is, because they completely believed in the "market omnipotence theory" and could not see that the blindness of the market led to overproduction in a certain field exceeding the purchasing power of the market, resulting in a serious loss of control and decline in the economy.

During World War II, the United States and the Soviet Union were allies, and the United States provided a large amount of assistance to the Soviet Union and also sent a large number of experts to help the Soviet Union manage it. Therefore, after the war, the United States seriously studied the advantages of the planned economy and abandoned the pre-war "theory of market omnipotence" and changed to a policy of taking the market economy as the leading factor and the state carrying out macroeconomic regulation and control. (Similar to today's argument in China, but the United States does not use executive orders as a means of macroeconomic regulation and control, but as a means of raising or lowering the loan interest rates of regulated industries) After using the "invisible hand" to carry out economic regulation and control, the United States' economic management ability and level have been greatly improved, and the US economy has entered a stage of rapid development after the war.

The post-World War II U.S. economy can be roughly divided into four phases:

First: the period of coordinated recovery after the war (the establishment of the Bretton Woods system) (1944---1962).

Due to the astonishing attrition and losses of World War II, the reserves of various countries were almost exhausted, and Europe and the countries of the world continued to recover as the biggest winner of World War II, the United States, and the Bretton Woods system was established with the standard of holding the dollar and the United States. Europe flourished in the early days of its founding, and recovered quickly.

Second: Crisis and stagflation (collapse of the Bretton Woods system) (1962---1973).

The capitalist world economy has grown and gone, and by the 60s, the United States' ** reserves declined; The dollar crisis became the direct cause of the collapse of the Bretton Woods system; the oil crisis caused by the war in the Middle East; and the consequent increase in inflation in the United States; and the Vietnam War had an even worse effect on the U.S. economy. In the early 70s, the Bretton Woods system collapsed, and the United States announced that the dollar and ** exchange rates floated freely.

Third: Neoliberalism (recovery phase) (around the 1980s and 90s).

Reagan Politics! After Fu came to power, he pursued a neoliberal policy: the state intervention in enterprises was basically abandoned, and the enterprises themselves resumed and adjusted, and the national economy gradually recovered.

Fourth, the period of rapid development of high technology (--- 1992 to the present).

With the disintegration of the Warsaw Pact bloc, the United States stopped the arms race, and with the huge economic foundation and the fruits of recovery, it began to systematically promote the high-tech development of all walks of life in the United States. Since Clinton took office, the United States has made systematic high-tech development in all walks of life, except for the traditional pillar industries of the United States, such as aerospace science and technology, aviation science and technology, shipbuilding, and biotechnology, and the United States has once again completely consolidated its position as world hegemon.

And as Europe, with the support of the Marshall Plan of the United States, relying on the original industrial and technological reserves, in the 60s, the old capitalist countries have basically recovered, and the Marshall Plan is too detailed, it will be hx, you can check it yourself.
